Disk Space Usage

There was an issue with the “old” template as it came without a specific <index_order>. In this case, the hrStorageIndex was used as the index. For existing filesystems, this will unfortunately change in case a new filesystem is added or removed. This way, the old template cuased issues on re-indexing.

Now, you may add <index_order>hrStorageDescr:hrStorageIndex</index_order> to the XML file manually or use the new template. This will have effect on all newly created data sources. But old data sources will not change.

Here's a script that applies the new <index_order> to all existing data sources. This way, you will be able to keep all existing data sources and have the correct index_order applied.

Script to reorder existing data sources of a given data query

This is a pure SNMP based replacement of the standard cacti disk usage templates. It requires support by the non-standard HOST MIB, however.

1. untar the attached resource file
2. Drop hrStorageTable.xml into your <path_cacti>/resources/snmp_queries/ folder.
3. Import the cacti087d_data_query_snmp_-_hrstoragetable template via import feature
4. Add the Data Query to a device.
5. From the 'Create Graphs for this Host' screen, select the required disks and click Create.
